Glutathione (IV/IM) vs PQQ
A side-by-side research comparison of Glutathione (IV/IM) and PQQ across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Glutathione (IV/IM) | PQQ |
|---|---|---|
| Full name | L-Glutathione (Reduced, Injectable) | Pyrroloquinoline Quinone (BioPQQ) |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | Compounded / Prescription | Dietary supplement (GRAS) |
| Mechanism | Directly conjugates with toxins, heavy metals, and reactive oxygen species via glutathione S-transferases. Regenerates vitamins C and E. Maintains thiol redox status. Supports Phase II liver detoxification. | Activates PGC-1α (master mitochondrial biogenesis regulator) via CREB phosphorylation. Catalytic antioxidant that undergoes 20,000+ redox cycles vs one-time use of vitamin C. Stimulates NGF synthesis for neuroprotection. |
| Molecular weight | 307.32 Da | 330.21 Da |
| Half-life | ~2-3 hours (IV bolus) | ~3-5 hours |
| Bioavailability | 100% (IV); ~60% (IM); ~5-10% (oral) | ~60% oral |
| Typical dose | 600-2000 mg IV push or 200-600 mg IM | 10-20 mg |
| Frequency | 1-3x weekly | Daily |
| Route | Intravenous push or intramuscular injection | Oral capsule |
